[plt-scheme] sake problem

There was a problem in the sake package that was just raised on IRC:

  copy-file: cannot open destination file; cannot copy:
  /usr/plt/collects/launcher/sh to: /usr/plt/bin/sake
  setup-plt: error: during Launcher Setup for
  <planet>/schematics/sake.plt/1/0 (Sake)

looks like sake is trying to install a launcher.  This is bad because
when people see this they might (as the IRC case went) switch to the
root user and run setup-plt again, which will recreate some files as
root which makes a bigger problem now with the user not being able to
touch these files.
